System compatibility

JAD-FC100C belongs to Yaskawa Yasnac CNC controller family,matched with Yasnac old CNC systems and CACR-SR servo drives. Widely used in precision machining centers and CNC grinders requiring full closed-loop control. This is a discontinued legacy full closed-loop interface board for high-precision machine tool maintenance spare replacement.

Function

JAD-FC100C serves as high precision full closed-loop servo interface board. It receives and decodes linear scale feedback signals,transmits actual table position data back to CNC main controller to realize full closed-loop position control. It converts and forwards servo commands between CNC host and servo amplifier. Built-in signal noise filtering circuit to suppress interference from workshop environment. It improves machine tool positioning accuracy and eliminates ball screw error.

Installation

Mount JAD-FC100C inside CNC controller cabinet. Complete backplane bus and linear scale wiring according to wiring drawing. Backup CNC servo parameters before replacement,verify full closed-loop positioning accuracy after power-up.

Interface

‑System backplane bus connector

‑Linear scale encoder input port

‑Servo signal exchange terminal

‑Onboard signal decoding and filtering circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Stable high-resolution signal transmission,strong anti-interference performance for industrial cabinet environment. Standard factory firmware preloaded.

Feature

JAD-FC100C is obsolete Yaskawa Yasnac series spare part. Typical failures include linear scale port pin damage,signal distortion,position reading drift. Check board integrity and connector pins before replacement. This board must match corresponding Yasnac CNC controller,direct substitution without closed-loop function test is not recommended.

Diagnostic

When linear scale signal loss,position feedback deviation or hardware communication timeout occurs,the board triggers corresponding alarm codes and sends fault signal to CNC main controller.

Built‑in function

Linear scale signal decoding,full closed-loop position feedback,servo signal conversion,signal noise filtering,position monitoring,used as CNC full closed-loop interface board spare replacement.

Product Brief

JAD-FC100C is Yaskawa Yasnac CNC series full closed-loop servo interface board for high-precision CNC machine tools and precision automation equipment. Confirm CNC controller model matching before ordering. ESD protection required during handling and installation.
